ings of its abdomen, Nectarophora gra?iaria Kirby ; it is, however, 

 larger, with much shorter nectaries and much broader tail, while the 

 apterous form, on account of the short nectaries comes near Nectar o- 

 pliora fulvee Oestl., though it is considerably larger and differs be- 

 sides in the conspicuously broad tail. 



Taken at Juneau, Alaska. 



Type. — Cat. no. 5274, U. S. National Museum. 



NECTAROPHORA INSULARIS sp. nov. 



Apterous female: General color evidently green. Eyes brown; 

 antennas black, the two basal joints, and the basal two-thirds or more 

 of joints three and four pale. Legs pale, the coxae brown, apex of 

 tibice, the tarsi and the tip of nectaries dusky to black. The body is 

 marked with a subdorsal row of nine small dusky spots, of which those 

 on the prothorax and mesothorax are elongated ; there are also two me- 

 diodorsal spots on the metathorax ; four still smaller dorso-lateral 

 spots in front of nectaries and four minute ventro-lateral spots. In some 

 of the immature specimens the nectaries are almost black. 



Length of body to tip of tail 3 to 3.4 mm., antennae rather long, 

 reaching to or beyond tip of tail and about 4 mm. in length. Length 

 of nectaries 0.7 to 0.8 mm. ; tail about 0.3 mm. Length of third an- 

 tennal joint about 0.7 mm. ; fourth joint 0.6 mm. ; fifth joint 0.5 mm., 

 and the sixth, with its spur, 2 to 3 mm. in length, the spur being 

 much longer than joint three. The first joint is very stout and almost 

 twice the length of the second ; the third joint is provided with one to 

 three small sensoria near its base. Nectaries slender, slightly tapering 

 and curving outwards. Hairs of antennae minute and simple, those 

 of the tibial stout and spine-like, a few of them sometimes slightly 

 thickened at the tip. 



This species resembles somewhat Nectarophora pisi Kalt., but is 

 much larger, the legs shorter and stouter, the nectaries shorter and the 

 tail broader. 



Obtained on St. Paul Island, Bering Sea.
